Using the Parametric Equalizer effect
The Parametric Equalizer provides maximum control over tonal equalization. Unlike the
Graphic Equalizer, which provides a fixed number of frequencies and Q bandwidths, the
Parametric Equalizer gives you total control over frequency, Q, and gain settings. For example,
you can simultaneously reduce a small range of frequencies centered around 1000 Hz, boost a
broad low-frequency shelf centered around 80 Hz, and insert a 60 Hz notch filter.
The Parametric Equalizer uses second-order IIR filters, which are very fast and provide
very precise resolution, even at lower frequencies. For example, you can precisely boost a
range of 40 to 45 Hz.
